The main object of this invention is to so improve' the patenteddei'icethat it can read- -11`y be pp'iied toV existing Vvwin'ilowranieeonstructions Without `requiring anyfmateriai changes therein rorin the `Win/dow sa'shes.

With these and other vobjects in View my 'invention vconsists in theconstruction,'combination andv 'arrangement o1" parts as will behereinafter more fiiliy described andvdeiined in the appended claims.

Fixed Centrally in and extending trans#A versely of the two adjacentslidewaysbearing the yielding housings 10 is ak plate 19 whichlongitudinally and centrally is formed with` a U-shaped lbend 191 to fitaround the `bead or partition@ dividing said two adjacent slideWa'yS. YThis bead is cut yaway as at el about midways of theplate and the latteritself slitted along thercutout portion and-i straightened or flattenedas at 19? to form a bearing for a pivot 20. kThe Ainner faceoftheslideways at the back of the'said plate iscut out as at a1sufficiently? `to l accommodatega"plate shaped lever `arm i321 which isfulcrumed onsaidpivot20` and which is capable of swinging in verticaldirection through the cut out space al. `This lever is adaptedto extendacross the rear face of the plate and has one of its ends 211 Y extendedso as to project forwardly through an arcuate slot a2 (Figp) provided in,the `front fa'ce of the Window frame to be ac- `cessible for the manualoperation thereof.

The plate 19 is provided with two openings 193 arranged midway onealongside the other in horizontal direction (Figs. 2 and l eachy adaptedto` coincide with a slide-r way The inner or rear member 11 of thehousing 1() is eut out ata certain place ofits length as at 112 to forma passage for `acam Vor tongue-'22 (Figs. 1, 3`andf4).

There may, of course, be more than one i cut out part in each member`11- when it is desiredrto have the sashes fasten' at differentelevations. `Said cam 22is adapted to act'upon the inner washer 16 ofthespring 14toA compressthe latter when it is desired to clamp and lock thesash against i vertical movement. `The cam 2.2 is inform 4of a plateextending transverselymof l,the islideway, and its inner or rearedge is`formed laterally with cylindridal projections 221,

222, adapted to serveas pivots and assuch rotatively engage; ears 194projecting rear! `wardly fronrthe plate 19.

AV spring 23 coiled around oneof said pivots and engagingwithone endsaid plate 1 9 and withits other end .abutting `against the tongue 22-A(Fig. 4)V has the tendencyto raise said tongue toward the housing sothat when the latter is` such position that its opening 112 is `just inalignment with the opening 193 in the 4plate 19 and with saidtongue, thelatter will passlthrough` thesaid openings engaging the* j rear or innerwasherlfreadyrto compress thespring 14. The tongue or cainl 22.` is` 'lffurther providedwitha rearwardly projecting nose223 which is adapted toengage an opening 212 in the lever arm 21 Vso that when be fastened.

\ ing Position.

i said arm is turned vertically on its horizontalpivot 20 it will forcesaid tongue 22 against the washer 16 compressing the spring 14 therebytightening the member 12 against the sash or when moved in oppositedirection it will collapse said tongue so that the latter will lieflator substantially in a hori- `zontal plane within the correspondingopening 193` of the. plate and out of engagement` the presentexamplethe. openings 112 in.. the

members 11 are arranged so that `when both sashes are in `closedposition the same] can I n order to make this clamping and fastening 'ofthe sashes automatiqfl providefthe following mechanism. i,

Pivoted to the lever arm "'21 at 213,` and adapted to Vextend downwardlyat the rear of the plate 19 is a resilient element or armV `24. T helower end 241 of Vsaid member 24 is formed to a cam shaped hook facingthe 4'platev 19. The latter for the extent equal to tha'tofthe movementof the lever is cut out as at 19` and an opening 11a is providedin saidrear plate 11 Vof the housing 10 at such place, that when Aafter closingthe upper sash and moving the lower sash into closing( position, .saidopening 11a will be expose( through the opening 19 of the plate andpermit the hook 241 of said resilient member 24 `which inthe unfastenedposition of the Y lever 21 pro'ects into the opening 19, to passinto saiopeningll.` `By a continued movement of the lower sashfinto the closingposition `the arm 24`will` be pulled down` therebyalso turning the lever21'into fasten- As the sash,` approaches the extreme lower end of theslideway the hook 241 owing toits cam shaped outer face slidingo'ver`the lowerfedge of the Vopening 1 9 is gradually'withdrawn from theopening,`

,711a to lie outside of the housing 10 '(Fig.

11). @Thus thefastening leverk19 is operated Y automaticallyv when thesaslies are moved into l `closing-position rand there is nofd'anger ofleavingfthe sashes' unfastened by Vforgetting Y to move'jthe lever 19.v`The unfastening of"v `the sashes canheeasily effected by moving thelever inopposite' direction, in which it is .assisted by the tendencyAof the springs j `of the cams 22.

f case thereaIe-several fastening positions of the sashe's theexpansible casing 10m] has several'openings 112,the casingisfcorrespondingly providedwith several openings 11 arranged atcorresponding intervals` apart Yin a vertical row to "causethe auto 1the front face of the bead e.

pansiblehousings- But due tothis play an opening 25 is `formed 'betweenY the front face` offthebeade and rear yfaces c1 of thewmdow sashesthrough which air and rain could pass. Toremedy-this, one of`the-housings 10, in this example the housing 10 for the lower sash, isprovided with a lateral extension 101 of substantially square shapedcross sections (Figs. 2 and 3) and of a length equal to that of therecess formed by the cut away portion e1 of the bead so as to more orless snugly fit therein. When the sashes are clamped by the expansion ofthe housing 10 this extension 101 will just lie flush with lhen it isdesired to remove the sashes from their housings, the sashes will haveto be first brought into closing position, so that the extension 101will be in alignment with the cut away part e1. In this position thesashes can be pressed laterally in the direction. of the yieldinghousings 10, the extension 101 being thereby caused to pass into therecess e1. In this position the sash can be removed first from thestationary housing 18 and then from the yielding housing 10.

Suit-able friction actuated means may be provided to prev-ent thehousings 10, 18 from sliding up in the slideways'under the action of thecounterweights, after the sashes have been removed from their housings.

Vlien for washing the windows it is not desired to remove the sashesentirely from their housing, the same can be just swung inwardly ontheir pivots 26, after the expansible housings 10 have been unclamped orslackened. Since various changes may be made in the construction withoutdeparting from the principle of my invention, I do not wish to limitmyself to the details shown and described.
